Feta lasts 1–2 weeks in the fridge, 6 months in the freezer, and no more than 2 hours at room temperature.
USDA FoodKeeper has no separate entry for feta. It is covered by “Cheese (soft such as brie, bel paese, goat)” (soft cheese), so this page uses that entry’s storage times.

Check your feta
Still inside the 2-hour limit. Put it in the fridge straight away, in a shallow container so it cools quickly.
Fine at normal room temperature. On a hot day above 32°C (90°F), 1 hour is already the limit, so refrigerate it immediately.
Two hours is the USDA cut-off. If it was warm, or you are not sure exactly how long, throw it out.
Past the 2-hour limit. Bacteria may have multiplied or produced toxins that reheating will not destroy.
Feta left out overnight has spent many hours in the danger zone (4–60°C / 40–140°F). It may look fine, but it is not safe.
Room temperature means anything above 4°C (40°F). On hot days above 32°C (90°F), the limit is 1 hour.
At -18°C (0°F), feta is still within the 6 months quality window. Thaw in the fridge and use within a day or two.
At -18°C (0°F), feta is still within the 6 months quality window. Thaw in the fridge and use within a day or two.
Still safe, and at the end of its best-quality window. Use it in the next few weeks; texture and flavour fade after 6 months.
Food kept frozen solid stays safe indefinitely, but after 9 months expect freezer burn and dull flavour. Fine for soups, sauces and baking; trim dry grey patches.
Food kept frozen solid stays safe indefinitely, but after 12 months expect freezer burn and dull flavour. Fine for soups, sauces and baking; trim dry grey patches.
Assumes a freezer at -18°C (0°F) or colder. Frozen food stays safe; these verdicts are about quality.
About feta
Feta belongs to our dairy & eggs category. USDA FoodKeeper has no separate entry for feta. It is covered by “Cheese (soft such as brie, bel paese, goat)” (soft cheese), so this page uses that entry’s storage times. According to USDA FoodKeeper, it keeps 1–2 weeks in the fridge and 6 months in the freezer. Like all perishable food, it should not sit at room temperature for more than 2 hours. Where to keep it: a middle shelf is best, not the door: the door warms up every time it opens.
Cheese is milk preserved by acid, salt and the removal of moisture, so it keeps far longer than milk. How long it lasts depends mostly on moisture: hard, aged cheeses keep for weeks or months, while soft and fresh cheeses behave more like fresh dairy and keep only days to a couple of weeks once opened.
Feta storage times by method
| Method | Duration | Temperature | Container | Notes |
|---|---|---|---|---|
| Pantry / counter | 2 hours | 68–72°F | Airtight | 1 hour if above 90°F |
| Refrigerator | 1–2 weeks | ≤ 40°F / 4°C | Airtight | at or below 40°F (4°C) |
| Freezer | 6 months | 0°F / -18°C | Freezer bag or wrap | at 0°F; quality, not safety |
Where to store feta
A middle shelf is best, not the door: the door warms up every time it opens.
Feta shelf life, answered
How long does feta last in the fridge?
1–2 weeks at 4°C (40°F) or colder. Count from the day it was cooked, opened or bought.
How long does feta last in the freezer?
6 months for best quality at -18°C (0°F). Frozen food stays safe indefinitely; after that, texture and flavour fade.
How long does feta last at room temperature?
No more than 2 hours, or 1 hour above 32°C (90°F). Perishable food left out longer should be thrown away.
How long is feta good for past the expiration date?
For perishable feta, the storage clock matters more than the label: if it has been in the fridge longer than 1–2 weeks, discard it even before the printed date.
How can you tell if feta is bad?
Ammonia or a sharp sour smell beyond the cheese's usual aroma. Slimy surface, or very dry and cracked all the way through. Darkened or yellowed edges, or new colours that are not part of the cheese.
How long can feta sit out?
2 hours at room temperature, 1 hour on a hot day above 32°C (90°F). Overnight is always too long.
Signs feta has gone bad
Smell
Ammonia or a sharp sour smell beyond the cheese's usual aroma.
Texture
Slimy surface, or very dry and cracked all the way through.
Colour
Darkened or yellowed edges, or new colours that are not part of the cheese.
Mould
On hard cheese, cut 1 inch around the spot. On soft or shredded cheese, discard.
Nothing ticked? Good sign. Still check how long it has been stored: the bacteria that cause food poisoning are invisible.
Any of these means it has gone bad. Throw it out — don't taste it to check.
Why feta goes bad
Mould is the main way cheese goes off. On hard cheese, mould roots cannot travel far, so you can cut away at least 2.5 cm (1 inch) around and below a spot. On soft, shredded or crumbled cheese, mould spreads unseen through the whole piece, so the whole piece should be thrown away. Bacteria also produce an ammonia smell as soft cheese ages past its best.
Common feta storage mistakes
- Wrapping it tightly in cling film, which traps moisture and encourages slime and mould.
- Cutting mould off soft or shredded cheese and eating the rest.
- Leaving it out for hours on a cheese board in a warm room.
- Freezing soft cheese and expecting the same texture.
Can you freeze feta?
- 1Step 1
Cut or portion into blocks of ½ lb or less, or freeze shredded cheese in its bag.
- 2Step 2
Wrap in plastic, then a freezer bag, pressing out air.
- 3Step 3
Thaw in the fridge; it will be crumblier, so use it melted or cooked.
How to thaw feta
In the fridge
Move it to the fridge the night before; texture holds best.
At room temperature
Only for shelf-stable foods; perishable food should not thaw on the counter.
From frozen
Many foods go straight into soups, sauces, smoothies or the oven.
Feta left out overnight
Feta left at room temperature for more than 2 hours (1 hour above 90°F / 32°C) should be thrown away. Bacteria multiply fastest between 40°F and 140°F, and reheating does not remove every toxin they make.
Bacteria multiply fastest between 4 °C and 60 °C (40–140 °F).
Best-by and use-by dates on feta
Best-by and sell-by
FoodKeeper gives unopened feta 1–2 weeks in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
For perishable feta, the storage clock matters more than the label: if it has been in the fridge longer than 1–2 weeks, discard it even before the printed date.
How to store feta
- Wrap in wax or parchment paper, then loosely in plastic, so it can breathe.
- Store in the cheese drawer or a lower shelf at 40°F (4°C) or below.
- Use a clean knife each time to avoid introducing mould.
How to pick fresh feta
- Buy hard cheese in a piece rather than pre-shredded if you want it to last longer.
- Check that packs are sealed and free of moisture or mould.
- Buy soft cheese in amounts you will finish within its opened window.
Feta: use it up in time
- Grate and freeze hard cheese for cooking.
- Melt it into sauces, toasties, gratins and omelettes.
- Use soft cheese in dips, pasta or baked dishes before its window ends.
Feta vs similar foods
- Shredded cheese 1 month
- Hard cheese 3–4 weeks
- American cheese 3–4 weeks
- Feta 1–2 weeks
- Cream cheese 2 weeks
- Brie 1–2 weeks
- Cottage cheese 1 week
Same scale as the timeline above: 1 hour to 2 years.
Check any food in seconds: when your leftovers expire, and whether something left out is still safe.

True or false? Feta myths
- Correct!Not quite.
False. The bacteria that cause food poisoning rarely change the smell. Stick to the 1–2 weeks window and throw out anything older.
- Correct!Not quite.
False. Freezing pauses bacteria; it does not kill them. They become active again as the food thaws, so thaw in the fridge and cook or reheat properly.
- Correct!Not quite.
Only partly. Quality holds for about 6 months at 0°F / -18°C. Texture changes, so use it in cooked dishes.
- Correct!Not quite.
False. The door warms up every time it opens. A middle shelf is best, not the door: the door warms up every time it opens.
- Correct!Not quite.
False. Some bacteria make heat-stable toxins. Reheating kills bacteria but not those toxins, so food left out more than 2 hours should be thrown away.
